At what age can you determine sex for lavender orpington?

[Megaletta]

Hello, first time chicken owner. We got three chicks in late July (born on July 22 2020) - a lavender orpington, a blue ameracaunna, and a salmon faverolle. The Salmon Fav just started laying last week (yay!). My lavender orpington was generally the most tame and friendly. In the past few weeks, she seems to be puffing up her chest and pecking at me (hard). When the others peck it is out of curiosity, but this seems more protective in nature. Being 7 months, would I know by know if it is for sure a hen and not a rooster? Added a few pics below. If she is still developing, I guess we could see longer tail feathers and spurs, but if not she is maybe just a feisty hen? (Or is there anything else I should be concerned about?)

Looks like you just have a feisty hen in your hands. At 7 months she would have crowed by now.

That’s a pullet

Since she’s about 30 weeks old, I’m guessing she’s already started to lay or is going to very soon.

The reason for her behavior is most likely because she’ll be laying soon, and wants to show her dominance.

Thanks all!!

Pullet.

100% pullet. If she's not already laying I'd be surprised with that red comb and wattles.

She’s a pullet. Looks like she’s getting ready to lay by her red comb and wattles.
